I am brand new to Verizon. Just got the Samsung Galaxy S3 yesterday, and so far, with every call, there is a constant double-beep that sounds like a call-waiting soun or notification alert, but I have the notification control set to "silent". It is not call waiting, because there is no name on the screen identifying a waiting caller. It is very annoying. I am the only one who can hear the beep. The person I am calling cannot hear it. I have tried pulling the battery and uninstalling/re-installing all apps. Nothing helps. I have contacted the store where I bought it. So far, nothing has fixed it. Please help!
